External txt file question

Hi I’m new here (great site btw!)
I’m faily new to flash too as it happens.
I’m creating a site and want to use dynamic text using external txt files. The thing is, is it possible to have multiple dynamic text boxes using the same txt file but each displaying a different section of the txt file; is there something you can put in the txt file, like say section1= bla bla bla…
The reason bieng, I want each page to have small text boxes instead of one large one, and I don’t want to be having separate txt files for each of them.
I don’t mind having txt files for each page.
